Using the track marker
At preselect Change when the implement is lifted out, the job computer activates the track marker valves. If work is started without activating the tractor control unit, there will be a misalignment. The active track marker folds in partially due to the ground resistance. The opposite track marker is partially extended due to the oil overflowing.
To prevent the track markers from moving into a misaligned position:
Activate the green tractor control unit .
